- A
Use a Job resource to process requests in batch
Why wrong: Jobs are for batch processing, not real-time inference serving.
- B
Deploy a single large pod on a powerful node
Why wrong: This vertical scaling approach lacks elasticity and fault tolerance.
- C
Use a Horizontal Pod Autoscaler (HPA) with target CPU utilization
HPA dynamically adjusts replicas based on real-time metrics, optimizing resource usage and latency.
- D
Set a fixed number of pod replicas equal to the maximum expected load
Why wrong: Fixed replicas waste resources during low demand and may not handle spikes if underestimated.

AI0-001 AI Infrastructure and Technologies Practice Question
This AI0-001 practice question tests your understanding of ai infrastructure and technologies. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team is deploying a machine learning model on a Kubernetes cluster. They need to ensure low-latency inference and efficient resource utilization. Which approach should they use to dynamically scale inference pods based on request volume?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a Horizontal Pod Autoscaler (HPA) with target CPU utilization
The Horizontal Pod Autoscaler (HPA) is the correct choice because it automatically scales the number of inference pods based on observed CPU utilization or custom metrics, ensuring low-latency inference by adding replicas during traffic spikes and reducing waste during idle periods. This dynamic scaling aligns with the need for efficient resource utilization in a Kubernetes cluster, as it adjusts pod count in real-time to match request volume without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that batch processing (Jobs) or static scaling is suitable for real-time inference, when in fact dynamic scaling with HPA is required to balance latency and resource efficiency in Kubernetes.
Detailed technical explanation
How to think about this question
The HPA works by periodically querying the Kubernetes Metrics Server (or custom metrics API) to collect resource usage metrics, then calculates the desired replica count using the formula: desiredReplicas = ceil[currentReplicas * (currentMetricValue / targetMetricValue)]. For inference workloads, using custom metrics like requests per second (RPS) via Prometheus can provide more accurate scaling than CPU utilization alone, as CPU may not directly correlate with request volume due to model inference being I/O or memory-bound.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
